Boost for aviation biofuels as ASTM completes revision of standard specification

ASTM International, an international standards organisation, has completed its process of approving the revision of ASTM D7566 (Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons) to include alcohol to jet synthetic paraffinic kerosene (ATJ-SPK) derived from renewable isobutanol. 

In a press statement, US biofuels producer Gevo said its alcohol-to-jet-fuel is now eligible to be used for commercial flights.

The fuel will specifically be used as blending component in standard Jet A-1 for commercial airline use in the US and in many other countries around the globe.

Gevo’s product is eligible to be used for up to a 30% blend in conventional jet fuel for commercial flights. 

"We have been eagerly awaiting the completion of the ASTM approval process. With this significant milestone achieved, we look forward to making the first test flight with Alaska Airlines a reality,” Dr Patrick Gruber, Gevo’s CEO.

He added: “We fundamentally believe that our ATJ is one of the most cost competitive bio-based jet alternatives in the market place, and we anticipate being able to announce further partnerships across the aviation industry in the near future.

“Jet fuel is one of Gevo's core market segments and this ASTM revision represents the next step in building a profitable business from this market vertical.”
